.DISCUSSION...
LOWER-LEVEL MOISTURE WILL CONTINUE ITS INCREASE TODAY ACROSS MUCH
OF OKLAHOMA. MODELS HAVE BEEN AND STILL ARE QUITE CONSISTENT ON
THE TRACK OF THE STRONG UPPER LOW FROM WESTERN TO NORTHEASTERN
COLORADO DURING THE DAY TUESDAY WITH A DRYLINE INTO WESTERN
OKLAHOMA BY AFTERNOON. INSTABILITY IS EXPECTED TO BE LARGE FROM
AFTERNOON WITH INCREASING STRONG VERTICAL SHEAR. ISOLATED SEVERE
THUNDERSTORMS ARE EXPECTED ALONG THE TRILLION IN AREAS WHERE THE
CAP IS SUFFICIENTLY WEAK DURING TUESDAY AFTERNOON. VERY LARGE
HAIL IS EXPECTED AND A FEW TORNADOES MAY OCCUR. COOLING ALOFT INTO
THE EVENING SHOULD HELP INCREASE THE NUMBER OF STORMS DURING THE
EVENING THROUGH THE I-35 REGION AND AREAS EAST. A SECOND SHORT
WAVE TROUGH IS FORECAST TO PASS THROUGH CENTRAL TEXAS INTO
SOUTHEAST OKLAHOMA LATE IN THE EVENING FURTHER ENHANCING
THUNDERSTORM DEVELOPMENT LIKELY IN AREAS EAST OF ARDMORE AND ADA.
PERSISTENT STRONG SHEAR AND LOW LCL VALUES WILL MAY LEAD TO AN
INCREASE IN THE RISK OF TORNADOES THERE. ONCE THIS SYSTEM PASSES
ON WEDNESDAY, LOWER LEVEL MOISTURE REMAINS NOT FAR AWAY TO RETURN
LATE THURSDAY AND FRIDAY. ANOTHER LARGE UPPER TROUGH WILL APPROACH
FRIDAY WITH A GOOD CHANCE FOR HEAVY RAIN AND SEVERE WEATHER. THIS
SYSTEM IS FORECAST TO BE SIMILAR TO THE ONE TUESDAY. LATE IN THE
WEEKEND A COOL FRONT PASSES AND BRINGS COOLER AND DRIER AIR.
